Recent NASA missions to asteroids have used robotic explorers to gather data about the early evolution of our Solar System, planet formation, and how life may have originated on Earth. To design successful robotic explorers, researchers must understand how these explorers impact the surface of asteroids during their touchdown. Researchers conducted lab experiments to determine what happens when explorers and other objects touch down on complex, granular surfaces in low gravity environments.
